We study the formulation of massless higher-spin gravity on AdS3 in a gauge in which the fundamental variables satisfy free field Poisson brackets. This gauge choice leaves a small portion of the gauge freedom unfixed, which should be further quotiented out. We show that doing so leads to a bulk version of the Coulomb gas formalism for WN CFT’s: the generators of the residual gauge symmetries are the classical limits of screening charges, while the gauge-invariant observables are classical WN charges.
